An Easy Entry into Berbane and Alloyohimbane Alkaloids via a 6-exo Radical Cyclization
摘要:
[GRAPHICS]The pharmacologically important tetracyclic berbane and pentacyclic alloyohimbane structures were prepared efficiently in four steps including a stereoselective 6-exo radical cyclization using xanthates as the radical source.
